Virtual Colonoscopy Allows Detection of Unsuspected Cancers Beyond Colon

ScienceDaily (Mar. 25, 2010) — A new, large-scale study of more than 10,000 adults found that more than one in every 200 asymptomatic people screened with CT colonography, or virtual colonoscopy, had clinically unsuspected malignant cancer and more than half of the cancers were located outside the colon. The findings were published in the April issue of the journal Radiology.

"We are finding that virtual colonoscopy screening actually identifies more unsuspected cancers outside of the colon than within it," said lead author Perry J. Pickhardt, M.D., professor of radiology and chief of GI Imaging, at the University of Wisconsin School of Medicine & Public Health. "As with asymptomatic colorectal cancers identified by virtual colonoscopy screening, these cancers are often detected at an early, curable stage."

Colorectal cancer remains the second leading cause of cancer death in the U.S., and the National Cancer Institute estimated that there would be 146,970 new cases diagnosed in 2009 and 49,920 deaths.
